With the help of Perl and a couple of CPAN modules, I was able to write up a small script that downloads email from a POP3 email account and stuffs the emails, headers, and attachments into dated (YYYYMMDD) directories. This is something I've been wanting to do for sometime and I finally got around to writing most of it Sunday night.
So thanks to Graham Barr for writing Net::POP3, Eryq for writing MIME::Tools (MIME::Parser), and Sullivan Beck for writing Date::Manip. To all who contribute to CPAN and Perl, thank you for making my job easier.
